regmap: No multi_write support if bus->write does not exist
There is no multi_write support available if we cannot use raw_write. This is the case if bus->write is not implemented. This patch adds a condition that we need bus and bus->write so that can_multi_write is true. Signed-off-by: Markus Pargmann <mpa@pengutronix.de> Signed-off-by: Mark Brown <broonie@kernel.org>
